Next, the operation of the hulling sorter will be described. When the hulling work is performed, the hulling is supplied to the hulling hopper 6 of the hulling unit 1 and the rotating units of the machine are driven. Next, the paddy is supplied from the paddy hopper 6 to the paddy rolls 7, 7 and padded, and the paddy rice is supplied to the paddy rice wind selection path 10 below. Then
The light rice husks are discharged outside through the suction fan 13 and the dust tube 14, and the relatively light pity grains are dropped and sorted into the pity receiving trough 11,
Heavy mixed rice of unpolished rice and paddy is dropped and sorted into a sliding rice receiving trough 12.

The selected mixed rice is fried by the mixed rice fryer 4, and the mixed rice hopper 24, the distribution and supply gutter 16
, And through the distributing case 17, the swinging sorting plates 15, 15,.
Supplied to When the swinging sorting plate 15 is reciprocated up and down in the horizontal direction, the mixed rice is reduced in size due to the size of the granules, the specific gravity, the coefficient of friction, etc. Paddy which has a drift distribution and is large in size and light in specific gravity as compared with brown rice is drift-distributed to the rocking side, and mixed rice which is not separated is sorted while being distributed in the middle thereof.

The sorted grains distributed in a non-uniform manner on the discharge side of the swinging sorting plates 15, 15 are divided into brown rice partitioning plates 18 and paddy partitioning plates 19.
The brown rice is taken out of the machine through the grain guide plate 20, the brown rice channel 21 and the brown rice milling machine 5, and the mixed rice is mixed rice discharge gutter 22, the mixed rice channel 23, the mixed rice frying. Grain machine 4,
Mixed rice hopper 24, distribution supply gutter 16 and distribution case 17
After that, it is circulated and supplied to the oscillating sorting plate 15 to be sorted again.
In addition, the paddy is a paddy take-out gutter 25, a paddy channel 26, and a paddy-fryer 27.
Is returned to the hulling unit 1 and the hulling is performed again.

Next, based on FIG.
The configuration of the grain take-out section provided to face the discharge side of 5, will be described. In the upper part thereof, a brown rice partitioning plate 18 and a paddy partitioning plate 19 are arranged, and a grain extraction gutter 28 is arranged in a lower part thereof. . The grain extraction gutter 28 is a brown rice channel 2 that is inclined upward and downward in the horizontal direction (the horizontal direction in FIG. 5).
1, and a mixed rice extraction gutter 2 that rises upward and swings upward
3, the brown rice channel 21 and the mixed rice channel 23
Of the mixed rice flow path 2
The lower end of the slope 3 communicates with the sloping rice receiving gutter 12.

At the lower end of the brown rice partition plate 18, a grain guide plate 20 for guiding the partitioned grains upward or downward is attached. The brown rice guide plate 20 is pivotally supported at a lower end portion of the brown rice partition plate 18, and the brown rice swing upper guide plate 20 a that guides brown rice that has been partitioned to the swinging side of the brown rice partition plate 18 to the swinging side, and a brown rice partitioning plate 20. A mixed rice swinging lower guide plate 20b fixedly attached to a lower end portion of the plate 18 and guiding the mixed rice partitioned on the swinging side of the brown rice partitioning plate 18 to the swinging side; A second mixed rice swinging side guide plate 20c which is pivotally supported by the inclined lower end of the plate 20b and guides the mixed rice down to the swinging side.

Then, the brown rice partitioning plate 18 moves to the highest swinging position, and is located above the swinging end of the swinging sorting plate 15, and all the grains distributed on the swinging upper side of the swinging sorting plate 15. Can be separated to the lower side (left side) by the brown rice partitioning plate 18, the mixed rice lowering side guide plate 20 b and the second mixed rice lowering side guide plate 20 c become the longest state (the state shown by a solid line). ), The lower surface portion of the second mixed rice swing lower guide plate 20c is supported at the branch point between the brown rice flow path 21 and the mixed rice flow path 23. Thus, the configuration is such that the whole amount of the grain partitioned on the swinging side (left side) of the brown rice partitioning plate 18 can flow down and be guided to the mixed rice flow path 23. In this state, the brown rice swinging upper guiding plate 20a is in a hanging state.

When the brown rice partition plate 18 is positioned above the inclined upper end of the mixed rice flow path 23 which is an intermediate position shown by a two-dot chain line, and the brown rice is widely partitioned and the sorting efficiency is increased,
The lower end of the brown rice shaking upper guide plate 20a contacts the upper side of the brown rice channel 21 to maintain a relatively steep slope, smoothly guide the partitioned brown rice to the brown rice channel 21 side, The configuration is such that the mixed rice is guided to flow down to the mixed rice flow path 23 by the side guide plate 20b and the second mixed rice swinging lower guide plate 20c.

[0020] As shown in FIG.
In configuring the grain extraction gutter 28 by the 1 and the mixed rice flow path 23, the inclined upper end of the mixed rice flow path 23 is positioned more upward than the upper end of the brown rice flow path 21, so that the sorting efficiency is improved. When the brown rice partition plate 18 is widely partitioned, the brown rice swinging upper guide plate 20a becomes a gentle slope, and the brown rice is smoothly guided down the brown rice channel 21 and may fall to the mixed rice channel 23 side, and the sorting efficiency is reduced. There was a problem that it did not improve.

However, since the above configuration is adopted, the brown rice swinging upper guide plate 20a attached to the lower end of the brown rice partition plate 18 is steeply inclined even during high efficiency work in which brown rice is widely partitioned by the brown rice partition plate 18. The brown rice can be smoothly guided to the brown rice channel 21 side, and the drawbacks of the conventional device can be eliminated. Further, the brown rice partition plate 18 is further moved to the upper side than the upper end of the rocking separator plate 15, and the whole amount of grains distributed on the rocking upper side of the rocking selector plate 15 is reduced by the lowering of the brown rice partition plate 18. Can be guided to the mixed rice flow path 23 by the mixed rice shaking lower guide plate 20b and the second mixed rice shaking lower guide plate 20c and returned to the hulling unit 1, and the grain at the end of the work Granulation can be performed quickly.

Note that, as shown in FIG.
In the configuration, even in the configuration in which the inclined upper end of the mixed rice flow path 23 is positioned above the upper end of the brown rice flow path 21, the mixed rice flow path 23 is swung upward from the upper end of the brown rice flow path 21. The extended upper end extension portion 23a may be configured to be turned up and down by the switching lever 29. With this configuration, at the time of high-efficiency sorting in which the brown rice is widely separated by the brown rice partition plate 18, the brown rice swinging upper guide plate 20a is steeply inclined to adjust the upper end extension portion 23a downward to smoothly guide the brown rice to flow down. Can make sure brown rice flow 2
1 can be guided.

When the sorting efficiency is improved by moving the brown rice partition plate 18 to a wide partition position, the motor (not shown) is rotated forward in connection with the movement of the brown rice partition plate 18. The upper end extension 23a is pivoted downward, and the motor is reversed at a narrow partition position to rotate the upper end extension 23a.
May be returned upward. With this configuration, the mixed rice partitioned by the brown rice partition plate 18 flows down and guided to the mixed rice flow path 23, and the brown rice partitioned on the swinging side of the brown rice partition plate 18 smoothly flows down to the brown rice flow path 21. it can.

Next, another embodiment of the brown rice fryer 5 will be described with reference to FIG. In constituting the brown rice fryer 5, a lower case 5b in which a fry blade 5a is provided is provided with:
A fry cylinder 5c is connected in series, and a side plate of the fry cylinder 5c has a perforated plate 3
A dust suction tube 31 is provided through the suction fan 13, and the end of the dust suction tube 31 communicates with the suction portion of the suction fan 13. Thus, the bran generated at the time of the fry of the fry blades 5a is removed during the fry by being sucked and removed from the perforated plate 30, and a clean brown rice can be taken out. In the present embodiment, the dust-absorbing cylinder 31 is connected to the rear of the fryer cylinder 5c (the right side in the drawing). In the same direction). The perforated plate 30 may be a net.
